 * The rendered deleted-content widgets in `editorState`, optionally restricted to `[from, to]`,
 * ordered by position. Deleted content is rendered as widget decorations rather than document
 * nodes, so this is how the element and the position it is anchored at are recovered.
 *
 * Kept internal and surfaced only through the `getDeletedWidgets` plugin action, so consumers never
 * receive the plugin key or the decoration set (which would let them mutate plugin behaviour).
